likewise, talk of packing the supreme court is supremely irresponsible and should be rejected in the most extreme terms possible. what do you think the republicans will do the next time they win? if it becomes normal to reshape the supreme court every time a new president is elected, that is essentially rendering the court meaningless. there is a separation of powers for a reason, and the court needs to hold the executive accountable, not become it's play thing, or be forced to conform to the executive's will.
these people are what is called sore losers.
if there are specific issues that congress believes are worth legislating to overturn court decisions it does not like then it should.
but, stacking the court is the dumbest idea possible, and anybody proposing it should be thrown out of the room.
